In today's farming practices, the ducks commonly raised by people are the result of artificial domestication and selective breeding from wild ducks. Despite this process, they still retain certain biological traits that make them highly sensitive to environmental stressors. Among different duck breeds, Pekin ducks, for example, are particularly more sensitive compared to other types.
Environmental stress factors such as temperature fluctuations, loud noises, unfamiliar sights, or sudden changes in routine can significantly affect the growth and productivity of laying ducks. Especially during the mid-laying period, ducks become even more vulnerable to these stressors, which can lead to a range of issues. These include nervous tension, hormonal imbalances, and abnormal behaviors like reduced feeding, drinking, or movement. Such conditions can also disrupt normal metabolism, ultimately leading to decreased egg production or even a complete halt in egg-laying.
On rainy days, especially when thunderstorms occur, the stress level for ducks increases dramatically. The sudden sounds and flashes of lightning can cause severe distress, resulting in panic or erratic behavior among the flock.
To minimize these effects, several measures should be taken. First, ensure that ducks are kept dry and protected from rain by providing them with a well-ventilated, clean, and dry shelter. Second, maintain appropriate lighting levels to avoid darkness, which can increase anxiety. Also, keep the duck population at an optimal density to prevent overcrowding and reduce stress from social interactions. Third, farm workers should act calmly and consistently, avoiding sudden movements or loud noises that might startle the ducks. Additionally, it is important to restrict access to the area by strangers or other animals to prevent unnecessary disturbances. Finally, consider adding vitamin E and vitamin C to the feed, as these nutrients can help reduce stress and support overall health.
By implementing these strategies, farmers can create a more stable and comfortable environment for their ducks, promoting better health, higher egg production, and improved welfare.
